Anything particular about Usenet that makes it attractive? Modern mailing lists (and even ones that are now dead but accessible) are a treasure trove of information, and I've often privately mulled over my concern that there doesn't seem to be a concerted effort to save them. Having tried to track down old copies of the Linux mailing lists, and having run into indicators of others' quests (and dead ends), I know how fragile the situation is. As I've recently come to understand, the Internet Archive itself used to have its own mailing lists for handling discussion, which interestingly enough seem to no longer be accessible—perhaps even lost.
